If judging by that post which that user made, a bet of 1.008 odd and stake 1.4 million dollars this could have shown that even the least odd can't guarantee winning for long run, but when a prediction is exacted to what you bet then there is every chances of winning, and of course you can win that continuously but we should also know about how matches are played most times and it would go against our bet.
A friend of mine combined more than 20 games to get just 5 odds his idea was to make sure the games were as safe as possible so he picked odds less than 1.10 only which was really ridiculous to me..it doesn't matter how little the odds are it doesn't guarantee Profit, to cut the long story short he ended up losing the bet that he thought was hundred percent safe, there's nothing safe about gambling anything can happen.. don't get enticed by little odds they might be very tricky
